At the iHeartRadio Festival on Saturday in Las Vegas, Lady Gaga dedicated her song "Hair" to Jamey Rodemeyer, the 14-year-old Gaga fan who committed suicide last week after being tormented at school because of his sexual orientation.

"We lost a Little Monster this week," Gaga said, displaying a video of Jamey. His "It Gets Better" video mentioned Gaga and her music several times as he discussed the things that helped him get through the school day.

Before he ended his life, Jamey wrote to Gaga. "@LadyGaga Bye, Mother Monster. Thank you for all you have done, paws up forever," he tweeted.

"I wrote this record about how your identity is really all you've got when you're in school," Gaga said. "So tonight, Jamey, I know you're up there looking at us, and you're not a victim. You're a lesson to all of us. I know it's a bit of a downer, but sometimes the right thing is more important than the music."

During the song, an emotional Gaga turned to the crowd and said, "Bullying is for losers." She's vowed to meet with the president to establish anti-bullying laws. "I will not stop fighting. This must end," she tweeted. "Our generation has the power to end it. Trend it #MakeALawForJamey."
